Boxed In and Wrapped Up
If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm...

Bend That Bar
Bend it, but don't break it. Groups investigate the strength of different materials. Using a procedure in the seventh segment of a 22-part series on aviation, pupils determine how far a rod will bend. They determine the strength-to-mass...
Teach Engineering
Stop the Stretching
Stretch your teaching repertoire with an experiment on the elongation (stretching) and failure (break) of several materials. The point of the experiment is to design a composite material for chair webbing.

May the Force Be With You: Drag
Do not let friction drag you down! The 11th segment in a series of 22 focuses on the fourth force acting upon an airplane—drag. Pupils learn about the effects and causes of drag.
Teach Engineering
May the Force Be With You: Thrust
Force the plane through the air. The instructional activity introduces the force on an airplane that makes it go forward. Pupils learn how Newton's laws of motion apply to flight in the eighth segment of a 22-part unit on flight.

Acid Rain Effects
Get out the goggles and conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects. Young chemists observe and describe the harmful...
Teach Engineering
Design a Flying Machine
Wrap up the unit in one final design. Pairs use their knowledge of aviation to design new flying machines and record how their designs take into consideration the forces that act upon airplanes. The pupils determine whether their designs...

Strawkets and Weight
Learners investigate the effect that weight has on rocket flight. They construct a variety of straw-launched rockets that have different weights, observe what happens when the weight of a rocket is altered by reducing its physical size...
Teach Engineering
The Great Gravity Escape
Groups simulate an orbit using a piece of string and a water balloon. Individuals spin in a circular path and calculate the balloon's velocity when the clothes pin can no longer hold onto the balloon.

Rocks, Rocks, Rocks: Test, Identify Properties and Classify
Time is growing short. Teams work together to identify physical properties of rocks in order to determine the properties that would best suit their cavern shelter design.
Teach Engineering
Household Energy Conservation and Efficiency
Are your household devices eating up a lot of energy? Pupils investigate household energy efficiency through a set of activities. They find ways to improve energy efficiency and reduce consumption. This is the 21st installment of a...
Curated OER
I Don't Believe My Eyes!
Students develop their understanding of the effects of invisible air pollutants. In this invisible air lesson, students complete experiments with a rubber band air test, a bean plant experiment and by exploring engineering roles related...
Teach Engineering
Ranking the Rocks for Desired Properties
Math rocks! Cavern design teams determine the rankings of rock types based upon desirability points. The points are connected to the properties of the rocks and their usefulness in building a cavern.
Curated OER
Are Dams Forever?
Students consider the life span of dams, and what would happen if a dam falls apart. In this environmental impact lesson, students discuss what the purposes of dams are, how they could be damaged.
Teach Engineering
Energy Forms, States and Conversions
Even magicians can't make energy disappear. In a discussion-based instructional activity, young scientists learn about energy forms and conversions. They see how energy is neither created nor destroyed; it just changes forms. This is the...

The Energy Problem
Think you can solve the energy problem? You'll first need to know about current energy use. Analyzing a set of circle graphs lets scholars see where energy consumption is the greatest, both by sector and by household use. They develop a...
